Microsoft already updating Office RT Preview to final version

Windows RT users will be able to update to the RTM build of Office on the 26th.

Anyone buying a Windows RT tablet—including Microsoft's own Surface tablet—won't have to wait long to get their hands on the final version of Office 2013. Microsoft has already started delivering the update via Windows Update, meaning that it'll be available on October 26th, at least to English-speaking users.

The update, weighing in at around 580 MB, removes the "Preview" branding from the Office splash screens, as well as the gold bar found in each app advising users that they are running a preview release.

This update comes out ahead of schedule; Microsoft previously announced that Windows RT devices would first receive their updates in November.
